Yes! I know the exact solution. But I need to get the numerical solution of the differential equation. It is a warm up to a harder equation with similar problems.

Hi! Initially I want to get the numerical solution of this very simple system. x'(t)=(1-x(t))^(1/2) with initial condition x(2.1)=0.9975.Also I note that if I start with initial conditions in the maximum x(2)=1, the RK4 gives contant solution x(t)=1. That is the reason I have to start with...

Hi! I have to solve a system of two coupled nonlinear ordinary differential equations. In the function that defines the system there are terms with square root of the dependent variables. I tried to solve the system numerically but in the nmerical solution I get violent oscillations. Then I...
